Question

我有一个雄辩的查询，我想把一个字段转换成＆＃34; float＆＃34;。它是一个聚合值，此时它以字符串形式返回，这是查询的一个示例：

$productStats->selectRaw("
    product.id,
    TRIM(product.name) AS item_name,
    SUM(IF(order.order_paid_date BETWEEN '" . $start->timestamp . "' AND '" . $end->timestamp . "' AND order.order_type = 'order' AND (open_count > 0 OR click_count > 0), order_item.total_price, 0)) as revenue,
    COALESCE(CAST(SUM(IF(order.updated_date BETWEEN '" . $start->timestamp . "' AND '" . $end->timestamp . "' AND order.order_type = 'order' AND (open_count > 0 OR click_count > 0), 1, 0)) as SIGNED), 0) / CAST(SUM(IF(order.updated_date BETWEEN '" . $start->timestamp . "' AND '" . $end->timestamp . "' AND order.order_type = 'order', 1, 0)) as SIGNED) AS change_rate
");

revenue和change_rate目前以字符串形式返回，但我希望它们是浮动的。它们是计算值，因此我无法真正将属性转换添加到模型中。

编辑：我从每个评论的查询中删除了DECIMAL。

Answer 1

将它们添加到模型的$casts：

protected $casts = [
    'revenue' => 'float',
    'change_rate' => 'float',
];
